To allwhom it may concern: 7

Be it known that I, MORRIS KAPLAN, a

. citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Eyeglasses, of'

whichthe following is a specification.

This invention relates essentially to the 'method of mounting the lenses of aneyeglass, the fundamental object being to securely clamp the lenses in fixed relation to the mounting.

The invention is the lens to the mounting when the pivotal connection between the lens and strap of the mounting becomes loose. 1

It is well known that if the pivotal connection for holding the lens to the strap becomes loose the lens will shift relative to the pivot, then if any sudden shock isgiven to the lens it will break or if the pivotis fastened too tight the strap .will have a tendency to fracture the lens. r V r I The novel features of the invention are more fully described in the following specification and claims and illustrated in the accompaying drawing in which Figure 1 represents a'front elevation of an eye-glass embodying this invention. Fig' Q'is a'similar view of a portion of the eye- I glass on a larger scale. Fig.3 is a perspective view of a clamping device. 7 V

In this drawing is "shown an eye-glass.

A detent 0r shoe g is pivoted at hl to the .lower portion of the strap. This detent has a wedge or cam shaped portion tithe object V of which will be hereinafter described;

Fixedlto' the lowerportion of. the strap is a post j having screwthreaded upper end.- for engagement-with a nut is and a'washer.

m mounted'on the post; The upper portion of the 'postis split so that it can be spread by a toolto get better, engagement of the, v thread with the bore of the nut. The clamping devicefor lockingthe detentincludesa the: lens.

designed to provide readily accessible auxlhary devices for fastenlng pair of bifurcated arms a for coaction with the Surface of the lens. These arms straddle the detentjand the rear wall or crotch of the bifurcation will cooperate with the,

wedge portion of the detent. I The; tail end of the. clamp has an aperture for 'slidingly' mounting the device on the post. Springs 9- coacting with the upper and lower parts of the:,tail,{end:ofthe clamp will serve as cushions to-talze up any sudden given to 7 When it" is desired to tighten thelens to the mounting the nut is manipulated, to

move toward the axis of the lens, thus compressing the springs and hence movingthe clamp upwardly. The crotch of the clamp will ride up the wedge. or incline moving the free end of'the detentto engage with the rim of the lens. In :this arrangement the detent will hold the lens firmly against the upper extension although the screw 0 can be loose. The arms of the clamp byclosely embracing the surface of the lens, will Obviate wabble of thelens and consequent breakage of the same is avoided. a V
